EDGE-TQOL SHARPENER.

SPECIFICATION forming part of Letters Patent No. 751,077, dated February2, 1904.-

Application filed August 6, 1903. Serial No. 168,522. (No model.) I

To all whmn it Wtcty concern:

Be it known that I, WILFRID JACQUES, a citizen of the United States,residing at Woonsocket, in the county of Providence and State of RhodeIsland, have invented new and useful Improvements in Edge-ToolSharpeners, of which the following is a specification.

My invention pertains to edge-tool sharpeners; and it has for its objectto provide a simple and easily-operated device through the medium ofwhich shears and other edgetools may be provided with an even edge.-

The invention will be fully understood from the following descriptionand claims when taken in connection with the accompanying drawings,forming part of this specification, in which Figure 1 is a sideelevation, partly in section, of the sharpener constituting thepreferred embodiment of my invention. Fig. 2 is a transverse section, ona reduced scale,taken through the body and stone of the sharpenerinaplane in front of the clamp. Fig. 3 is a plan view of a portion of thesharpener. Fig. 4 is a detail transverse section taken in the plane ofthe line 4 4, Fig. 1, looking in the direction of the arrow; and Fig. 5comprises disconnected perspective views of the jaws of the clamp forholding the tool to be sharpened and the bracket for connecting saidclamp to the overhanging arm of the sharpener.

Similar letters designate corresponding parts in all of the views of thedrawings, referring to which A is the body of the sharpener, in which isseated a suitable stone B for grinding the edges of the shears and othertools to be sharpened.

C C are posts fixed to and rising from the body; DD,longitudinally-disposed guide-rods interposed between and supported bythe posts; E, a slide movable in the direction of the length of thedevice on the rods D; F, an arm carried by the slide and overhanging andextending in advance of the forward post C, and G a clamp carried by theoverhanging arm and having for its purpose to hold theshears or othertool during the sharpening thereof.

As best shown in Figs. 1 and at, the connection between the arm F andthe slide E is effected through the medium of the ball a on the formerand a socket b on the latter containing the ball. The socket is providedin its forward side, Fig. 4, with an inverted-T- shaped opening 0,through which the arm F extends. In virtue of the provision of the saidopening 0 it will be observed that the user of the device is enabledwhile moving the arm F to and fro longitudinally to swing said arm in ahorizontal plane, as indicated by dotted lines in Fig. 3, and therebyapply the full length of the blade to be sharpened to the stone B; alsothat the operator is enabled to raise the arm for the purpose ofexamining the edge of the blade.

The clamp Gr (best shown in Fig. 5) comprises a jaw (Z, having a stem 6,an aperture f, and a recess g, a jaw it, having a lug z' designed torest in the recess g of jaw (Z, a threaded aperture j, and a recess is,of obtuse-angle form in cross-section, and a screw Z, connect: ing thesaid jaws (Z and h. The recess k in the jaw h and the recess g and thelug [of the jaws (Z and lb, respectively, are provided in order topermit of blades of various shapes in cross-section being properlyplaced and secured in the clamp.

H is a bracket having a sleeve mto receive the stem 6 of clamp-jaw (Zand an apertured vertically-disposed head 92 adapted to rest in a bifurcation p in the forward end of the arm F.

I is a screw which secures the stem of the clamp+jaw (Z in the sleeve ofthe bracket H.

J is a threaded bolt which extends through the walls of the bifurcationp in arm F and the head a of bracket H, and K is a nut mounted on andserving in conjunction with the bolt to adjustably fix the bracket andthe clamp G with respect to the arin F.

The head a of the bracket H and circular enlargements (1 on the walls ofthe bifurcation 1) are provided on their perimeters with graduations r,as shown in Fig. 3. This to permit of the bracket and clamp being setfor the formation of the exact bevel desired on the tool to besharpened.

In the practical operation of my improved sharpener the clamp G isadjusted and adj ustably fixed and the shears to be sharpened aresecured in the clamp, as shown in Figs. 1 and 2, after which theoperator grasps either the shears or the clamp and moves the shears toand fro on and lengthwise of the stone, meanwhile pressing the shearsagainst the stone and moving the same crosswise thereof until thedesired edge is produced on the blade of the shears.

I have entered into a detailed description of the construction andrelative arrangement of the parts embraced in the present and preferredembodiment of my invention in order to impart a full, clear, and exactunderstanding of the same. I do not desire, however, to be understood asconfining myself to such specific construction and relative arrangementof parts, as such changes or modifications may be made in practice asfairly fall within the scope of my invention as claimed.

Hz ving described my invention, what I claim, and desire to secure byLetters Patent, is

1. An edge tool sharpener comprising a body, a fiat stone thereon, aguide-rail connected with and arranged above the-body, at

'one end of the stone, a slide movable on said guide-rail toward andfrom the stone, a socket carried by the slide and having an inverted-T-shaped opening in its forward side, an arm extending forwardlythroughthe T-shaped opening in the socket, and having a ball disposed in saidsocket, and tool-holding means carried by the arm.

2. An edge-tool sharpener comprising a body, a flat stone thereon, aguide-rail connected with and arranged above the body, at one end of thestone, a slide movable on said guide-rail toward and from the stone, anarm carried by the slide and overhanging the stone, and movablevertically and sidewise on the the stone, and having a bifurcation andcircular portions, on the walls thereof, provided with graduations, abracket having a vertical, circular head arranged in the bifurcation ofand pivotally connected to the arm, and provided with graduations, meansfor adjustably fixing said bracket with respect to the arm, and atool-holder carried by the bracket.

at. In an edge-tool sharpener, a tool-holding clamp'comprising a jawhaving a recess in its inner side, a jaw having a lug on its inner side,adapted to rest in the recess of the first-mentioned jaw, and alsohaving a recess in its inner side, of angular form in cross-section, andmeans for connecting said jaws.

5. In an edge-tool sharpener, the combination of a fiat stone, a fixedguide-rail arranged at one end of the stone, a slide movable on saidguide-rail toward and from the stone, an arm carried'by the slide andoverhanging the stone, and movable vertically and sidewise on the slide;said arm having a bifurcation in its forward end and circular portionson the walls of the bifurcation, provided with graduations, a brackethaving a vertical, circular head arranged in the bifurcation of andpivotally connected to the arm, and provided with graduations, means foradjustably fixing said bracket with respect to the arm, and atool-holder carried by the bracket.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

WVILFRID JACQUES.
